Leeann Specification of Letters Patent, I

Patented Nov, '2, 1911.,

Application flied January 14, 1911. Serial Ito, 662,678,

To all whom'it may concern:

Be it known that I, AUGUST Gnnrnnnaorr, a citizen of the United States,residing at Quincy, in the county of Adams and State provements in theconstruction of the said segments and to combine-therewith an adductorrod which is employed to bind the sections together so firmly that thesame cannot separate or open the joints between them,

Another object of my invention is to provide the sections of the seatwith a boreto receive the adductor rod, which bore is spaced between theup er and lower surfaces of the seat, is entirely concealed, andrequires the use of no fillet in connection with the adductor rod.

' A' further object of the invention is to combine with the saidsections or segments, and the adductor rod, securin devices at the endsof the adductor rod w ich are adjustable thereon, so as to tension theadductor rod and cause the same to firmly bind and secure the saidsections together, and also enable the adductor rod to be removed whenit is desired to disassemble the parts of the seat for the purpose ofrepairing or renewing any of the parts thereof.

A. further object of my invention is to effect improvements in thesecuring devices and tensioning devices forthe ends of the adductor rodso as'to adapt the said secur ing and tensioning devices also for use ashinge elements for mounting the seat to combine with said hinge elementsa pintle rod to prevent themirom casually turning and relaxing thetension of the adductor rod.

In the accompanying drawings-Figure 1 is a plan of a seat constructed inaccordance with my invention, with portions of the same broken away andin section. Flg. 2 1s a longitudinal sectional view of the same on theplane indicated by the line 2-2 of F g. 1. Fig. 3 is partly a plan andpartly a section of a modlfied form of my inventlon.

The seat lwhich is substantialiy annular in form comprises a series'ofsegmental sec tions which are preferably made of wood, but which may bemade of any other suitable material. Any desired number of. thesectionsmay be used. The seat shown in the present embodiment of myinvention comprises an outer section 2, an inner end section 3, and apair of side sections or segments at, the said segments or sectionsbeing connected together by radial tongue and groove joints 5., Theouter end section 2 is provided with a bore 6 which conformssubstantially to the contourthereof, so that it is spaced between theinner and outer edges of the said outer sections, and the said bore isalso disposed between and spaced from the upper and lower sides of thesaid section so that it is entirely concealed. The said bore 6, extendsfrom one end or jointed portion of the said section 2, to the other endor jointed portion thereof, and is composed of a pair of angularlydisposed bored arms 7 which meet at the center and open at the endsthereof, and a pair ofc omparativel'y short bored arms 8 which-extendfrom the ends of the said section and intersect and are angularlyrelated to the said arms 7-. This construe .tion of the bore of thesection 2 enables the same to be made with a boring tool or device Eachsegment or section 4 of the seat is provided with a bore 9 composed of apair ofangularly related communicating arms 1O which are bored fromopposite' ends of the said segment, and are so disposed that theyexactly register and communicate with the arms 8 of the bore 6 ofthe'outer end segment 2, when the segments are joined together. Theinner end section 3 of the seat is provided near its. ends with bores11, which communicate with'the bores 9 of the side or intermediatesegments 4, and extend to the rear outer side of said inner end sec-,tion at points a suitable distance from the ends thereof, and areprovided with counter bores 12. Hence the seat is provided with a borewhich extends almost continuously around the same and which isentirelyconcealed excepting at its ends, being spaced from the inner,outer and upper and lower surfaces of the segments of the seat. 7

An adductor rod 13 which is preferably made of steel or some other metalpossessing great tensile strength is extended through -arms 7 of thebore 6 of the outer end segment 2; The said adductor rod is providedwith screw threadsl i at its ends, and nuts 15 are screwed on thethreaded ends of the adductor rod and located in the countera fillet orany filling material whatever,-

ened on theadductor .rod as may bores 12 of the bores 1.3. In themodified form of the device shown in Fig. 4, the nuts 15 are shown asprovided at their outer ends with slits or kerts 16, for engagement by ascrew driver so that the same may be Iftight:

e required to tension the latter and cause the 'same by its tension tofirmly and securely bind the segments of the seattogether.

In the preferred form of the invention shown in the other figures of thedrawing,

the securing and tension nuts 15 are formed with rearwardly extendingarms 17 which project to a required extent beyond the rear or inner endof the seat and are provided with openings for the reception of a pintlerod 18 which also engages openings in hinge lugs 19 formed at the upperends of screws or bolts 20 which may be engaged with a support for thehinged end of the seat.

'It will be understood that by the provisionof the arms 17 of the nuts15, the said nuts in addition to their function in securing andtensioning the adductor rod, are also availed of and utilized as hingemembers for mountin the seat. It will be understood also, t at thepintle rod which connec'ts the hinge members formed by the said nuts, tothe hinge members 19, also serves to prevent the nuts from turningcasually on the ends of the adductor rod and loosening the tensionthereof. 4

The seat may be readilydisassembled by first removing the nuts from theends of the adductor rod and then separating the said segments. Hence inthe event that any segment of the seat becomes broken or warped,

or otherwise injured, itmay be readily removed and replaced by anotherat minimum expense, so that repairs may be readily and economicallyefi'ected. It Wlll also be understood that by my construction andlocation of the members of the bore, in the various segments of theseat, and. throughwhichbores the adductor rod extends, I am enabled toentirely dispense with the use of nothing being placed in thecommunicating bores of the segments of the seat, but the adductor rodwhich runs through and around the seat.

I claim I 1. A seat of the class described made up of a series ofsegmental sections and having a .bore extending continuously around thesame from one side and back to the same side, the said bore beingconcealed and being spaced from the surfaces of the seat, and acontinuous adductor rod extending throughout thebore and aroundthe seat,and securing and tensioning devices on the ends of the adductor rod andbearing against one side of the seat. i

2. A seat of the class described consisting of an annulus formed by aplurality of end and intermediate sections, one'end section and eachintermediate section having a bore extending therethrough from end toend,

spaced from the sides thereof and comprising annularly relatedcommunicating intersecting arms, the other end section being providedwith cross bores extending from its ends to its outer side andcommunicating with the bores of the intermediate sections, an adductorrod of less diameter than the bores of the intermediate and first namedend sections and extending through the bores of all of and connectingsaid sections, and tensioning and securing devices on the ends of theadductor rod-and bearing against the other end section.

3. A seat of the class described comprising a series of segmentalsections provided with communicating bores, an adductor rod extendingthrough the bores of the said sections, and securing and combining saidsections together, and securing and adjusting nuts on theends of thesaid adductor rods, said securing and adjusting nuts being provided withhim e portions, in combination with hinge members for attachment to asupport and a pintle engaging said hinge portions of said securing nuts,and said hinge members, and preventing said securing nuts from casuallyturning on said adductor rod.
